INJECTION ZAMAK

The zamak is the commercial name given to the alloy composed mainly of zinc and aluminum and some copper and magnesium. It is a non-ferrous and versatile material. Its composition gives excellent properties for the production of parts by injection molding in large quantities with high precision and reproducibility of details regardless of the machining process and reducing costs.

Parts made of zamak components used in automotive, construction, electricity, electronics, telephones, toys, sporting goods, decoration and clothing.

Advantages of zamak

Making parts by casting zamak has a number of advantages over injection parts manufacturing aluminum. These advantages translate mainly in saving time and money and best finishes of the pieces:

  • Zamak less accurate energy consumption for processing, since it melts at 400 - 420 °.
  • Injection of zamak pressure allows manufacturing parts in large volumes with high accuracy.
  • Parts manufacturing zamak injection allows easily reproduced every detail of parts regardless of the machining process and reducing costs.
  • Faster injection cycle.
  • Saving machining.
  • Parts made with Zamak allow better finishes and surface treatments (paints, chrome and zinc plated.).
